To all whom it may concern;

- Be it known that I, FREEMANLR; WILI lson,

J r., a citizen of. the United States, residing at Worthington, in. the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Car-Loading. Mechanism, of which the followingis a specification,.reference being had therein to the accompanying drawings.

' framework.

This invention relates to an improved mechanism for loading Vehicles such as railwaycars, 'itbeing particularly adapted for loading severalcars at the same time with maititeries of cars and assorting or screening and delivering coal. of varying degreesof coarseness to the different cars.

Figure 1 is a side elevation of my improved mechanism arranged to deliver coal to a series of cars, said cars being shown in cross-section and one side of the frame being removed. Fig. 2 is a plan View of the same. a perspective of. the lock devices. across-secti onthrough two parts of the chute. Figs. 5 and6 show details.

Any suitable framework for supporting the; operative parts of the mechanism may be em-n ployed.

In the 2, upon which are mounted the pairs of uprights or standards 3 4 5 6.

- 7 7 are beams secured rigidly to the uprights 4-. and 5, and 9 10 are beams rigidly secured to the uprights at their upper ends.

The truss-beams 11 serve to brace the entire 12; represents cross beams seated "in and rigidly secured to the beams 9 10.

- B represents the delivering and assorting mechanism as a whole, consisting of a pair of screens and a telescoping delivery-chute or end section. This mechanism is pivotally suspended from the cross-beams l2 bymeans of links or bars 13, which at their upper ends are pivotally connected to eyebolts 14, said bolts being rigidly secured in or tothe iwithout spilling. 1 18 19 are short chutes secured tothe upper ends of the screens, the purposeofwhich will Fig. 3 is- Fig. 4 is drawings, represents the frame- -work as a whole. v It consists of sill members beams 12. The links 13 at: their lower ends fare. pivotally'connected to straps or "hinge; members 15, rigidly secured to the sides of the screens andchute.

. PATENT OF ICE;

16 represents the upper and the lower- I inclined screen, 16? 17 the side plates,- and. '16. 17 the bottom plates, the latter being; perforated for a portion of their length} The.

lower screen-17 is flared, as shown at117,-to receive thelower end of the screen 16, which pro ects slightly over the upper. end of. the

screen 17, thereby insuring the delivery of theother the material from one screen to be hereinafter set'forth. I.

-At either end of the shaft 20,. which is journaled in bearings-20, secured upon the. Jbeams 7 7, are mounted pairs of eccentrics 21 22. In the outer ends of. the eccentric-rods 21 is .pivoted the shaft 23,- which; is rigidly i secured to thelbottom of the screen 16 at its; upper end, and in the outer ends of. the rods 22 is pivoted the shaft 24, which .is likewise? secured to the bottom of .the screen 17 a-titsi upper end. Anysuitable meansmayibeein-t ployed to rotate the shaft.20.j -In"the-draw-- ings I have shown apulley 25, keyed-to kthe shaft, with a belt 26, which leads to the source of power. ,The GCCGDtIICS:EHGgpIBfBI'Hblyi mounted with their points atmakimumthrow diagonally opposite to each oth'er',.-thereby =1 causing the two screens. to oscillate with'rew spect toeachotherwhen the shaft 20 is-rota-' i ted, the combined throw ofithe eecentricsat 151021 5 time being sufiicient to entirely. withdraw the"; end of theupper screen from'the IIlOubhfQfif-s thelowerone, thus insuring that no materia will be spilled between the screens.- a The perforations; in the screens 17 are dis-: continued at 17, as shown, and from-there onthe. bottom .plate of the screen. serves as a guide for the material to the telescoping'chute or end section 27. This chute 27 consists of.

a bottom plate 28 'andside plates. 29 and. is 5 constructed to fit around or telescope the lower end of the screen 17. Any suitable mechanism for introducing and withdrawingthis telescoping chute from the vehicle to be loaded or for lowering the chute into working position and. raising it out of the same, as well as any suitable means for securing the telescoping chute to the screen above it in such a manner that it will reciprocate with the screen, may be employed. For illustration I have shown the side plates 17 of the lower screen reinforced on their upper edges or provided with plates or angle-irons,- as indicated at 30. These reinforcements or angleirons are bent upward at 31 and have locking-levers 32, pivotally connected to their upturned ends, as shown at 33.

The telescoping chute or end section 27 is provided with antifriction-rollers 34, mounted onthesides ofsaid'chute. These rollers ride upon thereinforced edges or'plates 30 on the screen 1 7. An antifriction-roller 35, journaled in bearings 36, supported by bearing members37 secured to the uprights 3, serves to support the telescoping chute from its underside when the latter iswithdrawn from working position and minimizes friction in the raising and lowering of the chute.

The telescoping chute 27 is lowered into workingposition andwithdrawn'therefrom by means of ropes or cables 38, secured at either side of the ehute,as shown'at 39: Said ropes or cables are led off over sheaves or' pulleys 40, pivotally secured to the sides of the lower screen 1 7, thence backward and downwardover the sheaves or pulleys 41, pivotally secured to" the cross-piece 42, and thence to the drums or reels43. Said drum 43 is mounted upon the: same shaft with a gear-wheel 44, which meshes-with. a pinion 45 on the shaft 46, said shaft being rotated by means of a lever or handle47. A ratchet 48 and pawl 49 serve to lock the drums43 against back rotation;

When in normal working position, the locking-levers 32'inclose the lower rollers 34 of the telescoping chute 27 and cause the latter to reciprocate in unison with the screen 17. The ropes or cables 50, which serve to raise and" lower the locking-lever 32, are attached to the free ends of the levers and lead upward over sheaves or pulleys 51, pivotally-secured to the beams 9 and 10, thence downward to the pins 52 or 53, to which they are secured by means of rings, hooks, or similar devices.

In the drawings the full lines indicate the telescoping chute in working position ready to deliver coal to. the car, the dotted lines indicating the chute when withdrawn from the car. To withdraw the chute from working position, the locking-levers 32 are raised by means of the ropes or cables 50, the lower ends ofwhich are secured tothe lower pins 53 iniorder to hold the levers out of their normal working positions, The pawl 49 is then "released from the ratchet 48, and the ropes 38 are wound upon the drum or reel 43 until the outer end of the telescoping chute 27 is withdrawn from the car the requisite distance. V hen it is desired to introduce the chute into the car, the drum 43 is allowed to pay out rope until the lower pair of friction-rollers 34 engage with the stop formed by the upturned ends of the plates 30. The lockinglevers are then let down into normal working position, thereby locking the telescoping chute 27 to the screen 17 in such a manner that the former will reciprocate with the latter.

C indicates any suitable devicefor example, a hopperfro1n which the upper screen 16 receives the coal to be assorted.

D, E, and F represent cars to be loaded with the coal of varying degrees of coarseness. To secure this screening or asserting, the upper screen is provided with relatively small perforations, the screen 17 with somewhat larger ones, it being intended that the larger or lump coal shall be delivered into the last car from the telescoping chute 27. The chutes 18 19 receive the material from the upper portions of the screens 16 and 17, respectively, and are so arranged as to insure its delivery into the cars beneath them.

To provide against undue straining of the oscillating parts due to any clogging which might occur, I have provided means whereby the eccentric-rods will yield longitudinally should the strain on them become too great. The ends of the eccentric-rods are reduced in diameter, as shown at 21", and pass through eyes 54 in the strap-arms 54. Springs 55 are then placed over the rods and taper nuts 56 adjusted thereupon, the ends 21 being screwthreaded to receive the same. The spring is thus held in place between the nut 56 and the eye 54. If new the strain upon the eccentric exceeds a certain predetermined amount, the spring will yield and prevent the breaking of the parts.

When the mechanism is to be put in operation and a box-car, such as F, is to be loaded, the latter is brought up to such position that the door in its side will lie in the lines of the chute, and thereupon, by means of the devices at 38 39, &c., the sliding chute 27 is allowed to run down in its guideway along the chute which supports it until its lower end has entered the desired distance into the car. Then it is locked in position by allowing the lock-bar 32 to descend until the angle part of the bar engages with one of the wheels 34, it being let down by releasing the cord 50 from its holding device at 52. Thereafter the telescoping extension of the chute becomes practically rigid with the main parts thereof and is subject to the same reciprocatory movements acting to carry the coal which passes over the screens down into the car. After the car has been loaded the lock-bar 32 is again drawn up by the cord 50 to release the telescoping part, whereupon it can be moved longitudinally by means of the rope 38 and the winding devices until its end has been in the sense of this invention the said screens may be considered as chutes for directing the passage of the material to the telescoping end section or chute 27.

What I claim is- 1. The combination with a reciprocatingchute of the telescoping chute having its bottom and sides inclosing the bottom and sides of said reciprocating chute, the supporting devices for said telescoping chuteand the lock adapted to rigidly connect said chutes together, substantially as set forth.

2. The combination with a reciprocating chute of the telescoping chute arranged at one end thereof, the wheels 34 supporting the telescoping chuteon the reciprocating chute, and the gravity-lock 32- adapted to secure the said chutes together, substantially as set forth.-

3. In a screening and car loading mechanism adapted to deliver coal immediately from the screen-sections to the cars of a series, as

at D, E, F, the combination with the adjacent .oppositely-reciprocating screensections 16.

and 17 having the car delivering-chutes l8 and 19 directly connected thereto, one delivering directly to the car D and the other delivering directly to an adjacent car E, the telescoping chute 27 adjustably connected to the screen 17 and the lock for holding it rigidly with said screen 17, substantially as set forth.

4. In a mechanism for delivering material to a vehicle, the combination with a reciprocating chute of a telescoping chute supported thereon, means for adjusting the telescoping chute relative to the said reciprocating chute and the lock adapted to secure the said chutes rigidly together when they are in working relation to each other, substantially as set forth.

5. In a mechanism for delivering material to a vehicle, the combination with a reciprocating chute of the telescoping chute having its bottom and sides inclosing the bottom and sides of said reciprocating chute, the supporting devices for said telescoping chute, means for adjusting said telescoping chute longitudinally of said reciprocating chute, and means 7 for connecting said chutes so that they will reciprocate together.

In testimony whereof I afiix my signature in presence of two witnesses. FREEMAN R. W ILLSON, JR.
